python - 无法在 Windows 上的 Python 3.7.0a 上安装 Pillow

Question

我在 Windows 10 中使用 Python 3.7.0a2 和 Django (2, 0, 2, 'final', 0)。在迁移项目时出现以下错误：

ERRORS:
accounts.UserProfile.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
        HINT: Get Pillow at https://pypi.python.org/pypi/Pillow or run command "pip install Pillow".

然后我运行“pip install Pillow”命令，出现以下错误：

  During handling of the above exception, another exception occurred:

如何安装枕头？

Pillow 的预编译版本可在此处获得，但并非所有版本都包括在内。

只要您确保使用具有预编译二进制文件的版本（作为直接安装或在 pip/peotry/etc 依赖项列表中），一切都会奏效。

也许有人会有用。

只有在我将一些软件包更新到某些版本之后，我才能在虚拟环境中安装软件包Pillow ( )。7.0.0

我将包更新setuptools到最新版本（在那一刻，44.0.0）

并将包更新pip为19.2.3.

作为参考，我使用了： Python 3.8.0、 Django 2.2.8、 Virtualenv 16.7.9、 Windows 10 SL x64

对于带有 python3.7 的最新 Anaconda，可以使用枕头。使用以下命令安装它：

conda install pillow

之后，停用您当前的环境，然后再次激活环境，然后它应该可以工作了。（此步骤对于使其有效很重要）

尝试如下安装 Pillow（如果您使用的是 Python3）：

pip3 install pillow

这：（如果您使用的是 Python2）：

pip install pillow

Pillow 需要在 Windows 上编译。pip install Pillow尝试使用预编译版本，如果失败 - 它会尝试在本地编译它。

您正在使用尚未发布的 Python 3.7，我怀疑 Pillow 人员尚未为此准备预编译的二进制文件。

最简单的解决方案是降级到 Python 3.6。否则，您需要安装编译 Pillow 所需的一切。
